Boris Nemtsov, Russian Leader Who Was Critical Of Sochi Olympics, Is Killed

Boris Nemtsov, a leading opposition politician in Russia, was shot dead Friday in Moscow. He was 55.

Nemtsov, a former deputy prime minister, had been a vocal critic of Russian president Vladimir Putin. In HBO's Real Sports' segment previewing the 2014 Winter Olympics, Nemtsov said the Sochi Games were for Putin a "show for himself."

"This is a festival of corruption and mismanagement," Nemtsov told HBO. "We have 20 million poor people in this country. We have a problem in police. We have a problem in our hospitals. Putin spent $50 billion for what? For what?"
